    摘要: A semiconductor manufacturing process is provided. First, a substrate is provided, wherein a patterned conductive layer, a dielectric layer and a patterned metal hard mask layer are sequentially formed thereon. Thereafter, a portion of the dielectric layer is removed to form a damascene opening exposing the patterned conductive layer. Afterwards, the dielectric layer is heated to above 200° C. Thereafter, a plasma treatment process is performed on the damascene opening, wherein the gases used to generate the plasma include hydrogen gas and inert gas. Afterwards, a conductive layer is formed in the damascene opening to fill therein.

    摘要: A method of removing particles from a wafer is provided. The method is adopted after a process for removing unreactive metal of a salicide process or after a salicide process and having oxide residue remaining on a wafer or after a chemical vapor deposition (CVD) process that resulted with particles on a wafer. The method includes performing at least two cycles (stages) of intermediate rinse process. Each cycle of the intermediate rinse process includes conducting a procedure of rotating the wafer at a high speed first, and then conducting a procedure of rotating the wafer at a low speed.
